Description
Technical Field
The utility model relates to a suspension type anticorrosion device.
Background
According to the technical regulations on grounding design of electrical equipment, a grounding device basically adopts hot galvanizing for corrosion prevention, but the corrosion resistance of a hot-dip galvanized layer is poor, and the galvanized layer completely falls off in some areas with heavy corrosion within 1-2 years generally; after the galvanized layer is locally detached, the exposed steel surface is easy to locally increase corrosion, so that the IEEE Std 80-2000 guidelines recommend that galvanized steel is usually supplemented with cathodic protection as an anti-corrosion measure.
On the transmission line tower, the grounding down lead is often the most serious in the steel grounding device. Because the down conductor is positioned at the position from the ground to the underground, the moisture and the oxygen in the soil in the area are relatively sufficient, and the down conductor is often in the dry-wet change process, and the corrosive medium can repeatedly corrode the steel material to cause the serious corrosion of the part. In addition, the down lead bears the leading-in underground task of the leakage current of the power transmission line on the tower, under the action of the leakage current, electrochemical corrosion is accelerated, severe pitting corrosion of local steel materials of the down lead is easily formed, corrosion pits or breakage and the like are formed, and further the power transmission tower can be operated without a grounding device, so that the potential safety power supply of the power transmission line is caused.
